本文整理了Java中java.nio.Buffer.remaining()方法的一些代码示例，展示了Buffer.remaining()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Buffer.remaining()方法的具体详情如下：
包路径：java.nio.Buffer
类名称：Buffer
方法名：remaining

Buffer.remaining介绍

[英]Returns the number of remaining elements in this buffer, that is limit - position.
[中]返回此缓冲区中剩余的元素数，即limit-position。

代码示例

ByteBuffer bb =..

byte[] b = new byte[bb.remaining()]
bb.get(b);

/**
 * Returns true if the end of the compressed
 * data output stream has been reached.
 *
 * @return <code>true</code> if the end of the compressed
 *         data output stream has been reached.
 */
@Override
public boolean finished() {
 // Check if all uncompressed data has been consumed
 return (finish && finished && compressedDirectBuf.remaining() == 0);
}

void checkStartEndRemaining(int start, int end) {
  if (end < start || start < 0 || end > remaining()) {
    throw new IndexOutOfBoundsException("start=" + start + ", end=" + end +
        ", remaining()=" + remaining());
  }
}

 userBufLen -= len;
 userBufOff += len;

}
